St. Luke was declared a saint before the official canonization
process was instituted in the 12th century. He would have been declared a
saint to the bishop by those who knew him best and were familiar with his
life and merits. The local bishop would them make the decision. Today
only the pope can declare saints after years of study by the Sacred
Congregation for the Causes of Saints in the Vatican. The church does not
create saints. Only God can do that. The Church "screens" candidates for
sainthood to determine if they had a life worthy of emmulation. In other
words, do they make good role models. Also, the Church has to be assured
that the person is actually in Heaven. That is the reason that today a
number of miracles must be verified before a person can be declared a
saint.
Saint Mark was not canonized. He was proclaimed a saint by early
Christians because of his martyrdom. The canonization process did not
come into existence until the 12th century. In the primitive Church,
martyrs were immediately recognized as witnessing to the perfection of
Christian life on earth, having shown the ultimate proof of their love for
Christ by the offering of their lives. By the sacrifice of their lives
for Christ, they attained Heaven in eternal glory and were indissolubly
united to the Lord, the Head of the Mystical Body.
There is no St. Luke the Younger. There is a St. Luke the Evangelist, however. When Luke died there was no official process for canonizing saints. He would have been proclaimed a saint by those who knew him best, based on his life and merits. A bishop would then have declared him as a saint. Today the only person that can do that is the pope based on years of study by the Sacred Congregation for the Causes of Saints.
Luke was neither beatified nor canonized as the processes were not instituted until about 1000 years after Luke died. He was proclaimed a saint by the early Christian community probably just a few short years after he died.
St. Luke was believed to have been canonized as a saint by the early Christian Church, although the specific date of his canonization is not recorded in historical accounts.
my sources do not say
